摘要: The invention relates to an integrated circuit for contactless radiofrequency device connected a first antenna and second designed receive signal coming from reader. According main characteristic, the includes rectifier rectify each received antenna, respectively, so as produce two positive output voltages V1 V2, circuits being mounted in parallel order select voltage value that corresponds maximum between V2.
